Manganese Silicide 
Molecular formula: MnSi2 
English name: Manganese disilicide 
Density: 5.24g/mL 
Properties: soluble in hydrofluoric acid and alkali, insoluble in water, nitric acid, and sulfuric acid. Inorganic compound, gray octahedral crystal 
Synthesis method: Put 2g (0.036mol) of manganese, 2g (0.071mol) of silicon, and 10g (0.16mol) of copper in small pieces into a 10mL Al2O3 crucible and place it in a quartz ampoule with one end open. After evacuation and sealing, place the ampoule in a carbon silicon rod high-temperature furnace. Raise the temperature to 1200 ℃ within 12 hours, and then cool it down to 500 ℃ at a rate of 10 ℃/h. Remove the ampoule, cool it down, and then insert it into a thicker diameter rubber tube. Crush the ampoule so that the metal ingot can be safely removed. Dissolve the copper rich Cu Mn Si block in 8mol/L nitric acid, leaving behind the octahedral crystals. Wash these crystals with water and dry them to obtain MnSi2 crystals with edges up to 2mm in length. 
Application: Manganese silicide is a transition metal silicide and a type of refractory intermetallic compound. Due to its unique physical and chemical properties, it has been successfully applied in complementary metal oxide semiconductor components, thin film coatings, bulk structural components, electric heating elements, thermoelectric materials, and photovoltaic materials. High silicon manganese (MnSi1.7) is composed of abundant elements with excellent thermal and chemical stability, and is therefore considered by the industry as a thermoelectric conversion material. Its physical and chemical properties have been successfully applied to Cmos components, thin film coatings, block structured components, heating elements, thermoelectric materials, and photovoltaic materials. Its nanomaterials exhibit special electrical, optical, magnetic, and thermoelectric properties, and even have potential application value in the field of catalysis. Using manganese silicide thermoelectric conversion materials, the power factor of the output index reaches 2.4MW/K2m, which is about twice the original. By using materials, it is expected to achieve waste heat discharge from engines and industrial kilns, such as high-power thermoelectric modules that convert heat into electrical energy at 300-700 ℃. However, traditional metallurgical or physical preparation methods such as this method cannot meet the preparation requirements of transition metal silicide nanomaterials. However, the manganese silicide prepared by Haixin has the characteristics of high alloying degree, pure metal process, high purity, and low impurities. On December 1, 2016, Tohoku University in Japan announced the use of manganese silicide thermoelectric conversion materials, resulting in a power factor of 2.4MW/K2m representing the output index, which is approximately twice the original power factor. The use of materials is expected to achieve high-power thermoelectric power generation modules that convert unused heat into electrical energy from waste heat such as 300-700 ℃ emitted by engines and industrial kilns. 
Storage and transportation: Keep the storage container sealed, place it in a tight container, and store it in a cool, dry place
